May 29, 1937 In Sweden 10 Claims.

This invention refers to sashes, cases and frames and similar structures in which a pane of glass or other material is to be secured.

The chief object of this invention is to create an inexpensive and simple but very reliable arrangement for that purpose.

Another object of this invention is to secure such panes by means of moldings and the like without any visible screws on either side.

Another object of this invention is to render it easy to mount window panes, also by use of unskilled labor.

A further object of this invention is to render it possible to mount a glass-holding molding from one side of the window only, by first screwing screws into that side of the window, then placing the pane in correct position, and finally pushing the moldings on said screws in such manner that the screws are entirely covered by the moldings.

Still another object of the invention is to render it possible to mount mitered moldings by pushing them on the screw heads in the lateraldirection of the molding and towards the center of the window pane.

Another object of this invention is to exert a resilient pressure on the window pane, when mounted, so as to prevent breakage.

Other objects of this invention will be evident from the following specification and claims.

Some embodiments of my invention are shown in the annexed drawings.

Fig. 1 shows a vertical section through a window in accordance with this invention. I Fig. 2 shows a partial front view of the same window, some parts being cut away along the line IIII in Fig. 1, for showing the construction more clearly.

Fig. 3 shows a partial section through a window having crossbars.

Fig. 4 shows a partial section through another embodiment.

Fig. 5 shows a horizontal partial section through still another embodiment.

Fig. 6 shows a perspective view of the attachment plate as used in Fig. 5.

Fig. 7 shows a partial horizontal section through a modified embodiment.

Finally Fig. 8 shows a perspective view of the attachment plate as used in the embodiment shown in Fig. '7.

Referring now to Figs. 1 and 2 of the drawings l indicates the wall in which the window is placed. In the window opening in said wall rails 2 are secured in well-known manner, for in- -der the screws 6.

stance by means of screws 3 uniting the rails 2 with pieces 4 molded in the concrete wall I.

To the rails 2 profiled sheet metal rails 5 are screwed by means of screws 5b. At the upper edge of the window the rail 5 is extended at 5a to form a protection against the rain.

Into the rails 2 screws 6 are screwed in such manner that their heads are at a predetermined distance from the metal sheets 5 and the axes of their shanks lie perpendicular to the plane of the pane. The lower sides of the heads of said screws 6 are provided with recesses or slots 1. On these screws moldings 8 of profiled sheet metal are pushed. flange 3a bent inwards and also folded on its entire length so as to form a resilient tongue or plate. In this flange 8a recesses or slots 9 (Fig. 2) are cut, adapted to receive the shafts of the screws 6.

The glass pane proper I0 is secured between the moldings 5, 8 and rests on blocks H or the like at the lower side of the window. Holes [2,

l3 are cut in the moldings 5, 8 tofacilitate the circulation of air.

For mounting a window pane, the moldings 5 are first screwed in their correct position onthe rails 2 by means oiscrews 5b. Then the screws 6 are secured in their correct positions, gauges being used for ensuring a correct distance 3 between the moldings 5 and the lower Sides of the heads of the screws 6. Then the window pane It] is placed on the blocks II and the moldings 8 are placed in correct positions simply by pushing the flanges 8a with their recesses 9 un- At the corners the moldings are rabbeted in the usual manner, as shown in Fig. 2.

It is evident that the mounting procedure is very simple and requires little skill. When mounted, the window is safely secured in its 'place and the resilient molding 8 damps stresses on the window. The whole construction is simple, inexpensive and reliable.

When the window has cross-bars or window bars between the individual panes, the construction shown in Fig. 3 may be used. In this figure the cross bar l4 consists of a rectangular iron rail, into which the screws l5 are screwed in such manner that their heads are at a certain predetermined distance from the surface of the rail I 4. The heads of the screws [5 have slots or channels H5 in their lower sides. Moldings 11 are pushed with their flanges Ila, below the heads of the screws l5, in similar manner as the moldings 8 in Fig. 1. The moldings l5 thus The moldings 8 have one resiliently secured support and hold the window panes I8, [9 on both sides.

Fig. 4 illustrates how a window pane is secured on a wooden sash or frame 20. Into said sash, which may be movable or stationary, screws 2| are screwed, which are similar to the screws 6 and I and on these screws moldings 22 are pushed with their flanges 22a, just as the moldings 8 in Fig. 1. screws 2| are not actually perpendicular to the plane of the pane, the shanks nevertheless have an extent in a direction perpendicular to said plane so that similar components of resilient forces arise and the molding strip is resiliently pressed in a similar direction, that is, against the pane to be held. These moldings 22 hold the window pane 23 resiliently on both sides.

In the embodiment shown in Fig. 5, the window pane 24 is secured between two rigid moldings 25, 26. The molding 25 is somewhat Z-shaped and rigidly connected with the rail 2 in well-known manner, while the rail 26 is substantially U- shaped. In the sides of the rail 26 slots or channels 21 are cut, which are engaged by the edges of resilient locking or attachment plates 28, see also Fig. 6. Each plate 28 is substantially rectangular and is folded in its longitudinal direction a certain angle along the line 29. In the plate a hole 30 is out having an extension 31 extending across the edge 29.

After the molding 25 has been secured in its place and the window pane 24 has been inserted in its correct position, the moldings 26 are inserted in place. For this reason the plates 28 are in advance inserted into the channels 21 of the moldings 26 at those places, where the screws I5 are to be engaged. Then the molding 26 is laid on the molding 25 in such manner that the heads of the screws l5, which have in advance been screwed in correct positions, enter the holes 30. Then the piece 5 is pushed laterally (to the left in Fig. 5) in the plane of the window so that the recesses 3| receive the shafts of the screws l5 and the edge 29 enters the slot IS in the lower side of the screw head. Now the window pane is safely secured in place and the spring action of the plate 28 renders the whole construction resilient.

In the modified embodiment shown in Fig. '7 the Window pane 32 is supported on one side by a substantially Z-shaped molding 33, secured to the rail 2. On the other side the pane 32 is supported by a substantially U-shaped molding 34, on which the free edges are bent inwards at 34a to form flanges for holding the locking plate or molding 35, see also Fig. 8. This molding is bent or folded in opposite directions along the lines 36, 31, 38 and has two flanges 39, 40 adapted to engage the corresponding inner sides of the molding 34. At one side a slot 4| is cut in the plate 35 and said slot has an extension 42 extending across the central edge 36.

Prior to the mounting procedure the locking molding 35 is inserted into the interior of the molding 34. Such insertion may be made by pushing the molding 35 lengthwise into the molding 34 or by pressing the flanges 39, 49 in the direction against each other and inserting them in the opening between the flanges 34a of the molding 34. When the molding 35 has entered the interior of the molding 34, the flanges 39, 49 will spring apart and the two moldings 34, 35 assume the relative positions shown in Fig. 7.

For placing the combined molding 34, 35 on the screws I5, after the molding 33 and the pane Although the axes of the shanks of' 32 have been placed in correct positions, it is only necessary to cause the head of the screw I5 to enter the slot 4| and to 35 laterally in the plane of the Window 32, that is to the left in Fig. 7.

In Fig. 6 the plate 28 is shown as a relatively short clipping, while in Fig. 8 the plate 35 is shown as a continuous molding extending substantially along the entire edge of the window. These two embodiments are obviously equivalent and may be substituted for each other. The screws 6, 15, 2| are preferably manufactured by means of a casting process under pressure.

It is evident that theprofile shape of the moldings is to a certain extent arbitrary and may be varied at will, substantially in accordance with the aesthetic requirements in every single case.

In the embodiment shown in Figs. 1-4 the locking flange 8a, 11a and 22a is integral with with its molding and in Figs. 5-8 the locking flange or plate 28, 35 is secured to its molding 26 and 34, respectively, by spring action. However, the locking flange or plate may be secured to its molding by other means, for instance by riveting, by welding and the like.
